IGNITION-CAP FOR FUSES.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application led July 8, 1918. Serial No. 243,799.

To all whom it may concern:

Be it known that I, Louis V. ARoNsoN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Ignition-Caps for Fuses,of which the following is a specification.

This invention relates to ignition caps for fuses. In the lighting offuses attached to bombs and other forms of explosive carrying means itis the present practice to use matches, said practice being exceedinglydangerous and the cause of frequent premature explosions. The ordinaryfuse when lighted is consumed for about one inch of its length inapproximately two seconds of time, and it will therefore be seen thatthe lighting of the same by the useof matches must be accomplished withgreat care and celerity in order to avoid accidents. A furtherdisadvantage in the use of matches for this purpose is the danger ofsparks flying from the head of the match and thus causing ignition ofadjacent or reserve supply of bombs or other forms of explosives.

The object of my invention is to provide a cap or tip adapted to becarried separate from the fuse and to be, laced over the end of the samewhen it is esired to io'nite the fuse, the said cap containing at oneend thereof ignition and combustion means whereby when placed upon thefuse such ignition end may be ignited by friction, as in the case of anordinary match head, thus communicating fire to the fuse. A furtherobject of my invention is the provision of a cap or tip of thischaracter which is equipped with means whereby when placed upon the fuseit cannot be accidentall displaced therefrom by jarring, such as t edropping of the fuse before or after its ignition.

Other objects will be in part obvious from the annexed drawing and inpart indicated in connection therewith by the following analysis of thisinvention.

This invention accordingly consists in the features of construction,combination of parts and in the unique relations of the members and inthe relative proportioning and disposition thereof, all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend theunderlying features thereof that they may embody the same by thenumerous modifications in structure and rclation contemplated by thisinvention, a drawing depicting a preferred form has been annexed as apart of this disclosure, and in such drawings, like characters ofreference denote corresponding parts throughout all the views, in whichFigure 1 is a broken perspective view of a fuse equipped with myimproved cap or tip with an ignition head applied thereto;

Fig. 2 is a vertical sectional view of a fuse similarly equipped and,

Fig. 3 a View of a fuse and cap in disassembled relation, the cap beingshown without the ignition head.

i designates the ordinary fuse equipped at its lower end with a bag 5,indicated in Fig. 2 of the drawing as containing 'I. N. T. 6 designatesa metal cylinder provided between its ends with a series of inwardlyextending tangs 7 adapted to permit the cap (i to be slipped over thefree end of the fuse and preventing the accidental displacement of thesame therefrom, due to the free ends of said tangs impinging against orbiting into the body of said fuse in such withdrawal movement. The upperend of the cap 6 is provided with a corrugated surface 8 and over saidsurface, and filling the upper end of said tip, I provide a combustionmaterial 8', covered with a readily ignitible material 9, the wholetreated with a suitable water-proofing solution, all preferably of thematerials set forth in Patent No. 1,287,819, issued to me December 17,1918.

In practice my improved caps or tips will be shipped separate from thefuse, and such caps may be carried in a suitable receptacle in thepocket and when it is desired to ignite the fuse one of said caps isslipped over the end thereof and such equipped end of the fuse is thenignited by friction, as in the case of the ordinary match. As will beseen the side openings in the cap, due to the form of the tangs affordair openings which will assist in the combustion of the fuse.

The corrugations 8 formed in the outer end of the cap constitute aneffective seat for the combustion end, the material of which, as will beseen, extends over said ends and in said corrugations, thereby forming afirmer contact than would be the case were such combustion materialmerely placed in the end of the cap, and preventing the accidentalbreaking of said mass of material in applying the same to a frictionsurface to effect its lighting.

By means of my invention the danger of premature ex losions ismaterially lessened and time is ai'brded after the ignition of the fuseeither to place the bomb or to retreat to a. safe position therefrom andbefore the eX- plosion occurs.

It is believed that from the above it will be seen that the presentinvention provides e cap of simple and practical construction adapted toaccomplish, among others, all of the objects and advantages herein setforth.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. An ignition head or cap for fuses and the like, comprising a, hollowmember open at one end and `adepted to receive the fuse, and having itsopposite end of corrugated form, and closed et said end by a body;r of

ignitible and combustible material extending over said end and fillingthe corrugations therein.

2. A n ignition head or oap for fuses and the like, comprising a. hollowmember open et one end and adapted to receive the fuse, and having itsopposite end of corrugated form? and closed at Said end by a body ofignitible and combustible material extending over said end and fillingthe corrugations therein, and provided with means to prevent itsaccidental displacement from the fuse.

In testimony whereof I affix my signature in the presence of twoWitnesses.V
